Announced by DEFRA yesterday.

 Guess we need to get them all this year, the pre-emptive strike.

Or just switch to the ones based on ferrous sulphate.

Metaldehyde is very nasty.

I fully agree. Frogs and a hedgehogs consume a lot of slugs. It makes little sense to poison the creatures that are actually helping in the fight against slugs.
Not mad, just out to mulch!

Commercially, growers are switching to ferric phosphate, allegedly "harmless " to wildlife; but toxic to earthworms. There used to be a preparation of aluminium sulphate (alum) known as Nobble to contact kill molluscs. When/why it dissappeared is unknown to me, is it still around?, did it work?
 Mechanical means may be therefore preferrable, beer traps, sharp blades, stamping on wilted ,laid, comfrey leaves after 2 nights.
Any other proven methods, mechanical or chemical?

For my small patch I am very happy using nematodes. It is a bit pricey, but I think it is worthwhile if I can enjoy my hobby without too many setbacks. There is a Toby Buckland article (Telegraph) which talks about making your own nematode solution but I haven't tried it!

I tried nematodes for the first time this year, but in the end I only used them once as it was so dry!
Glad to see any measures to help our wildlife.

I started to use nematodes when hedgehogs began visiting. I did use ferric phosphate tablets for a while, but then decided to only use them from time to time in the greenhouse. I didn't realise they were toxic to worms though. Must have a read around on that!

My knowledge of the chemistry is limited but the substance has chelators added in manufacture, EDTA and/or EDDS, resulting in toxicity in lifeform cells, apparently.

Gardeners QT on R4 today insisted that Garlic Spray is effective - anyone here tried it?

Does one know what it does to be "effective"?
Deterrent (by being 'smelly'), decoy by masking the flavour of food, chemically irritant as in some physiological interference, or trigger a Francophobe reaction?.
I wish to locally eliminate, (or significantly reduce )the population of molluscs , within the 'island' of cultivation.This has previously relied upon use of metaldehyde and mechanical methods.
 Perhaps one can 'tame' a resident hedgehog or two, providing shelter and subsistance rations. Proven, control tested, suggestions are welcomed
